According to the above technical solution, the embodiment of the present invention has at least the following beneficial effects.

In the bubble machine of the embodiment of the present invention, the first through hole communicates the liquid collecting chamber with the liquid discharge hole; for example, the first through hole and the liquid discharge hole communicate through a conveying conduit. Therefore, the first driver can convey the bubble liquid in the liquid storage chamber to the first through hole from the liquid discharge hole and infuse the bubble liquid into the liquid collecting chamber. The second driver drives the film covering body in the liquid collecting chamber to rotate. During the rotation of the film covering body in the liquid collecting chamber, the bubble liquid is transferred to the film forming hole. The airflow generated by the blower moves to the film forming hole, such that the film formed on the film forming hole can form bubbles. During the bubble formation process, part of the bubble liquid on the film covering body and the film forming hole drops naturally due to gravity and vibration. The dropping bubble liquid will be wasted and stain other areas. To this end, the present invention communicates the second through hole on the mounting shell with the liquid collecting chamber and the liquid return hole; for example, the second through hole and the liquid return hole communicate through a conveying conduit. Part of the bubble liquid dropped from the film covering body and the film forming hole can be returned to the liquid storage chamber through the second through hole and the liquid return hole for use in a next cycle.

Referring to FIGS. 1 and 2 , the present invention provides a bubble machine 1. The bubble machine 1 can continuously blow bubbles to create an ambience; for example, an entertainment atmosphere for a stage. A housing 10 of the bubble machine 1 is provided with a push-pull handle 2. The push-pull handle 2 is slidably connected to the housing 10. As shown in FIG. 1 , the push-pull handle 2 can be slid to snug-fit with the housing 10, such that the push-pull handle 2 is in a stow-away state. This design can reduce the size of the bubble machine 1 to facilitate the stow-away of the bubble machine 1. As shown in FIG. 2 , the push-pull handle 2 can also be slid to form a holding space 21 with the housing 10, such that a user can pass one hand through the holding space 21 to hold the push-pull handle 2.

The bubble machine 1 includes the housing 10, a liquid storage tank 20, a film forming device 30, a blower 40 and a drive assembly 50.

The housing 10 provides a mounting space for the components of the bubble machine 1. The housing 10 may be made of metal, plastic or alloy, etc., and the material of the housing 10 is not limited herein. Referring to FIG. 3 , the housing 10 includes a first housing 11 and a second housing 12. The push-pull handle 2 is provided on the first housing 11. In other embodiments, the push-pull handle 2 may also be provided on the second housing 12. The first housing 11 and the second housing 12 enclose a mounting space 101. Components such as the liquid storage tank 20, the film forming device 30, the blower 40 and the drive assembly 50 are mounted in the mounting space 101, thereby realizing a compact overall structure of the bubble machine 1.

A battery mounting position 100 is further provided on the housing 10. The battery mounting position 100 is provided with a battery pack 1001. The battery pack 1001 is used to power the electronic devices of the bubble machine 1 such as the drive assembly 50 and various switches. The housing 10 is further provided with a battery cover 1002 to seal the battery mounting position 100.

The liquid storage tank 20 is connected to the housing 10. Referring to FIGS. 4 and 5 , the liquid storage tank 20 is provided with a liquid storage chamber (not shown) for storing bubble liquid. The liquid storage tank 20 is further provided with a liquid discharge hole 21 and a liquid return hole 22 which communicate with the liquid storage chamber. In this embodiment, the liquid discharge hole 21 and the liquid return hole 22 are provided on two opposite sides of the liquid storage tank 20 in a lengthwise extending direction. It should be noted that the mounting positions of the liquid discharge hole 21 and the liquid return hole 22 are not limited.

It should be noted that the liquid storage tank 20 is further provided with a liquid filling port 23 communicating with the liquid storage chamber. The liquid filling port 23 may be hidden or exposed through a push-pull cover plate 102 provided on the housing 10. When the cover plate 102 is pulled out, the bubble liquid can be injected into the liquid storage chamber through the liquid filling port 23. The cover plate 102 can be closed when it is not necessary to inject the bubble liquid.

The film forming device 30 is located on a side of the liquid storage tank 20 where the liquid return hole 22 is provided. Referring to FIGS. 6, 7 and 8 , the film forming device 30 includes a mounting shell 31 and a film covering body 32. The mounting shell 31 is provided with a liquid collecting chamber 310. The liquid collecting chamber 310 is used to collect the bubble liquid from the liquid storage tank 20 and return the unused bubble liquid to the liquid storage chamber in the liquid storage tank 20. In an embodiment, the mounting shell 31 includes a front shell 311 and a rear shell 312. The front shell 311 and the rear shell 312 are connected and enclosed to form the liquid collecting chamber 310.

The mounting shell 31 is further provided with a first through hole 31 a, a second through hole 31 b and film forming holes 31 c.

The first through hole 31 a communicates the liquid collecting chamber 310 with the liquid discharge hole 21. For example, the first through hole 31 a and the liquid discharge hole 21 communicates with each other through a conveying conduit. The second through hole 31 b communicates the liquid collecting chamber 310 with the liquid return hole 22. For example, the second through hole 31 b and the liquid return hole 22 communicates with each other through another conveying conduit. The film forming holes 31 c penetrate through the mounting shell 31 and communicate with the liquid collecting chamber 310. The film forming holes 31 c are used for the bubble machine 1 to produce a bubble film. In this embodiment, there are a plurality of film forming holes 31 c. For example, as shown in FIG. 7 , there are two film forming holes 31 c. For ease of understanding, the two film forming holes are defined as a first hole 3131 and a second hole 3132 here. The first hole 3131 and the second hole 3132 are on the same horizontal plane and are spaced apart. The first hole 3131 and the second hole 3132 penetrate through the front shell 311 and the rear shell 312 of the mounting shell 31.

The film covering body 32 is provided in the liquid collecting chamber 310 and is opposite to the film forming holes 31 c. The film covering body 32 is rotatably provided in the liquid collecting chamber 310. When the film covering body 32 rotates, the bubble liquid in the liquid collecting chamber 310 forms a film on the film forming holes 31 c. The bubble liquid film formed on the film forming holes 31 c can form bubbles under the action of airflow.

The blower 40 is opposite to the film forming device 30. In this embodiment, the blower 40 is located on a side of the liquid storage tank 20 away from the film forming device 30. The blower 40 is driven such that an airflow generated by it flows to the film forming holes 31 c, such that the bubble liquid film formed on the film forming holes 31 c can be blown up to form bubbles. The blower 40 includes a plurality of blades, which can be adapted to different airflows by changing the inclination and size of the blades.

The drive assembly 50 includes a first driver 51 and a second driver 52. The first driver 51 is used to convey the bubble liquid in the liquid storage chamber from the liquid discharge hole 21 to the first through hole 31 a and infuse the bubble liquid into the liquid collecting chamber 310. In this way, the film covering body 32 rotating in the liquid collecting chamber 310 can carry the bubble liquid in the liquid collecting chamber 310 to form a bubble liquid film on the film forming holes 31 c. The second driver 52 is used to drive the film covering body 32 to rotate, so as to allow the bubble liquid to form a film on the film forming holes 31 c. It should be noted that the first driver 51 may be a water pump, and the second driver 52 may be a motor. The second driver 52 can simultaneously drive the blower 40 and the film covering body 32 to rotate. That is, output shafts at opposite ends of the second driver 52 are respectively connected to the blower 40 and the film covering body 32. The design saves the number of motors and reduces product cost. It can be understood that, in other embodiments, the blower 40 may also be driven by another motor, which is not limited in the present invention.

The second driver 52 that controls the rotation of the film covering body 32 is also the power source of the blower 40. In order to obtain a larger airflow speed, generally, the motor rotates faster. In order to control the rotation speed of the film covering body 32, it is necessary to reduce the rotation speed of the output end of the second driver 52 connected to the film covering body 32.

To this end, the bubble machine 1 of the present invention further includes a speed reducer 60 and a rotating shaft 61. The second driver 52 is connected to the rotating shaft 61 through the speed reducer 60. The speed reducer 60 includes a turbine 62 provided on the output shaft of the second driver 52, and a reduction gear set 63 provided between the turbine 62 and the rotating shaft 61. The rotating shaft 61 can be driven to rotate to drive the film covering body 32 to rotate. In this way, the rotation speed of the film covering body 32 can be reduced.

In the bubble machine 1 of the embodiment of the present invention, the first through hole 31 a communicates the liquid collecting chamber 310 with the liquid discharge hole 21; for example, the first through hole 31 a and the liquid discharge hole 21 communicate through a conveying conduit. Therefore, the first driver 51 can convey the bubble liquid in the liquid storage chamber to the first through hole 31 a from the liquid discharge hole 21 and infuse the bubble liquid into the liquid collecting chamber 310. The second driver 52 drives the film covering body 32 in the liquid collecting chamber 310 to rotate. During the rotation of the film covering body 32 in the liquid collecting chamber 310, the bubble liquid is transferred to the film forming holes 31 c. The airflow generated by the blower 1 moves to the film forming holes 31 c, such that the film formed on the film forming holes 31 c can form bubbles. During the bubble formation process, part of the bubble liquid on the film covering body 32 and the film forming holes 31 c drops naturally due to gravity and vibration. The dropping bubble liquid will be wasted and stain other areas. To this end, the present invention communicates the second through hole 31 b on the mounting shell 31 with the liquid collecting chamber 313 and the liquid return hole 22; for example, the second through hole 31 b and the liquid return hole 22 communicate through a conveying conduit. Part of the bubble liquid dropped from the film covering body 32 and the film forming holes 31 c can be returned to the liquid storage chamber 310 through the second through hole 31 b and the liquid return hole 22 for use in a next cycle. This improves the reuse rate of the bubble liquid stored in the bubble machine 1.

In an embodiment, referring to FIG. 9 , the film covering body 32 includes a rotary wheel 321, a mounting piece 322, a first rod 323 and a second rod 324. A center of the rotary wheel 321 is fixedly connected to a rotating shaft 61. An eccentric lever 3211 is provided on a side of the rotary wheel 321 facing away from the rotating shaft 61. The eccentric lever 3211 is located at an edge of the rotary wheel 321. A track groove 3221 is provided on a side of the mounting piece 322 facing the rotary wheel 321. The lever 3211 is slidably provided in the track groove 3221. The first rod 323 and the second rod 324 are respectively rotatably connected to two opposite ends of the mounting piece 322. The first rod 323 and the second rod 324 are further rotatably connected to an inner wall of the mounting shell 31. The rotary wheel 321 and the lever 3211 can be rotated under the driving of the rotating shaft 61, such that the lever 3211 slides in the track groove 3221. The track groove 3221 plays a limiting role to drive the mounting piece 322 to move left and right. The first rod 323 and the second rod 324 are driven to swing left and right between the first hole 3131 and the second hole 3132 respectively, such that the bubble liquid forms the film on the first hole 3131 and the second hole 3132. The bubble liquid film formed on the first hole 3131 and the second hole 3132 can form bubbles under the airflow of the blower 40.

Referring to FIGS. 7, 8 and 10 , the film forming device 30 further includes a guide plate 33. The guide plate 33 is provided in the liquid collecting chamber 310, and cooperates with the mounting shell 31 to form a closed receiving chamber 330. An upper end of the guide plate 33 is provided with a guide hole 311 aligned with the first through hole 31 a. Two sides of a lower end of the guide plate 33 are respectively provided with a first diversion hole 312 and a second diversion hole 313 that communicate with the liquid collecting chamber 310. The first diversion hole 312 and the second diversion hole 313 are adjacent to the film forming holes 31 c and are located above the film forming holes 31 c. A first guide groove 314 and a second guide groove 315 are provided on a side of the guide plate 33 facing away from the film covering body 32. The first guide groove 314 and the second guide groove 315 are respectively located on two opposite sides of the guide hole 311. The first guide groove 314 and the second guide groove 314 communicate the guide hole 311 with the first diversion hole 312 and the second diversion hole 313, respectively. Based on the above structural design, the bubble liquid from the liquid storage chamber can slowly flow into and infiltrate the film forming holes 31 c. A small amount of the bubble liquid accumulated on the film forming holes 31 c can form a bubble liquid film under the swinging of the film covering body 32. This prevents the bubble liquid from accumulating in the film forming holes 31 c due to an excessively fast speed to make it difficult for the excess bubble liquid to form a bubble liquid film. In addition, this structural design does not require too much power of the suction pump, and does not require the suction pump to have a large suction force to absorb the bubble liquid.

In an embodiment, referring to FIGS. 6 and 8 , the bubble machine 1 further includes an air supply passage 41 provided opposite to an air outlet end of the blower 40. The air supply passage 41 is provided on a side of the film forming hole 31 c facing the blower 40. The airflow generated by the blower 40 can be sent out from the air supply passage 41 and flow upward, such that the bubbles formed on the film forming holes 31 c can be blown upward. Further, the bubble machine 1 includes an air outlet passage 42 provided opposite to the air outlet end of the blower 40. The air outlet passage 42 is provided below the film forming holes 31 c. The airflow generated by the blower 40 can be sent out from the air outlet passage 42 and flow upward, such that the blown bubbles can be driven to continue to float upward. This design can increase the height of the bubble blowing.

In an embodiment, as shown in FIG. 3 , the bubble machine 1 further includes a support frame 70. The support frame 70 serves as a support carrier for mounting the film forming device 30, the blower 40 and the drive assembly 50. In an embodiment, the liquid storage tank 20 is provided with a mounting groove 201, and the support frame 70 is provided in the mounting groove 201. In this embodiment, the mounting groove 201 penetrates to both ends of the liquid storage tank 20, that is, the mounting groove 201 can be understood as a U-shaped groove.

In an embodiment, the bubble machine 1 further includes a net 80. The net 80 is adjacent to the blower 40. The net 80 can play a filtering role to prevent outside large particles from interfering with the normal rotation of the blades of the blower 40.

Another embodiment of the present invention further provides a bubble machine 1. The bubble machine 1 can adopt any of the above-mentioned implementations, and the difference lies in the structure of the film covering body 32 of the bubble machine 1 in this embodiment.

Referring to FIG. 11 , in this embodiment, the film covering body 32 includes a rotating wheel 325 and a plurality of support rings 326. The plurality of support rings 326 are arranged along a circumference of the rotating wheel 325, and a part of the plurality of support rings 326 are opposite to the film forming holes 31 c. The rotating shaft 61 is fixedly connected to the rotating wheel 325. The rotating wheel 325 can rotate to drive the support rings 326 to carry the bubble liquid to the film forming holes 31 c, so as to allow the bubble liquid to form a film on the film forming holes 31 c. Under the action of the blower 40, the bubble liquid on the film forming holes 31 c forms bubbles through the support rings 326.

It should be noted that the plurality of support rings 326 are opposite to the film forming holes 31 c, such that the bubble machine 1 can form a plurality of bubbles at the same time. This design increases the number and forming speed of bubbles, and improves the user experience.

The present invention is described above with reference to several typical implementations. It should be understood that the terms used herein are intended for illustration, rather than limiting. The present invention may be specifically implemented in many forms without departing from the spirit or essence of the present invention.
